1. sqrt 52 = 7.211 rounds to 7

2. irrational number

3. sqrt 441 = 21....rational

4. 12^2 + 3^2 = h^2
    144 + 9 = h^2
     153 = h^2
      sqrt 153 = h
      12.4 = h <===

5. 6^2 + b^2 = 18^2
    36 + b^2 = 324
    b^2 = 324 - 36
    b^2 = 288
    b = sqrt 288
    b = 16.97 rounds to 17 <==

6. 39^2 + 52^2 = c^2
    1521 + 2704 = c^2
    4225 = c^2
    sqrt 4225 = c
    65 = c
    (39 + 52) - 65 = 91 - 65 = 26 miles shorter <==

7. 4^2 + b^2 = 16^2
     16 + b^2 = 256
     b^2 = 256 - 16
     b^2 = 240
     b = sqrt 240
     b = 15.49 rounds to 15.5 <==

Eddi Din [679]

Answer:

Concept: Higher Level Mathematics

  1. You have a density curve, aka probability
  2. You are asked to find the height
  3. Hence 0-40F has 40 total integers or values of X(probability)
  4. Hence you have a total Area of
  5. \binom{40}{0}
  6. Integrate f(x) to get 0.025.
  7. Hence the answer is A

A regular hexagon rotates counterclockwise about its center. It turns through angles greater than 0° and less than or equal to 3
Bogdan [553]
Hey there Caleb!

To start of, the sentence was clear on that it said . . . 

\boxed{A \ regular \ hexagon \ rotates \ counterclockwise \ about \ its &#10; \ center }

The statement listed above is the (key) point. We need to keep this in mind.

So, now that we know this.

We would use the mathematic (Ф)

So,sense we know that a (hexagon) had it's (6) shapes, we would do . . . 

Ф = 360° : 6 = 60°

Your correct answer to this question would be . . . 

\boxed{\boxed{60}}

Hope this helps.
